ULTRAAQUA · LARGE-SCALE DRINKING WATER UV DISINFECTION
CROSSFLOW Series
High-capacity UV systems for large municipal drinking water plants, with the lamps arranged across the flow in a compact stainless-steel reactor.
Pricing on request.
Overview
The CROSSFLOW series is built for large municipal drinking water facilities. Instead of running along the flow, the lamps are arranged across it in a CFD-optimised pattern. This keeps the reactor compact, improves hydraulic efficiency and lowers operating costs.
The reactor installs horizontally or vertically and fits into complex plant layouts with a small footprint. Systems can be scaled up as treatment demand grows.
Ozone UV Solutions supplies CROSSFLOW systems as an authorised ULTRAAQUA reseller and supports them locally: from sizing and installation through commissioning, servicing, lamps and spare parts.
Key features
